A general stochastic method for synthesizing compounds can be used to generate large collections of tagged compounds that can be screened to identify and isolate compounds with useful properties.

A diversity scheme for allowing a transmitter/receiver, such as a mobile unit in a mobile telecommunications system, to exchange communication signals with more than one control station, such as a base station or satellite. According to an exemplary embodiment of the diversity scheme, the mobile unit scans for the control channel of a second satellite during idle time slots while communicating with a first satellite during active time slots. Once the mobile unit detects a control channel from a ...

In a diversity receiver, each of first and second diversity branches includes an antenna and a high-frequency amplifier coupled thereto. A diversity decision circuit is coupled to the outputs of the amplifiers to generate a switching control signal identifying one of the outputs of the diversity branches having a higher field intensity value. A power switching circuit is provided for coupling a voltage source to one of the amplifiers according to the switching control signal so that power supply...

Two or more signal paths are provided for receiving a radio frequency signal. One or more signal paths include conventional bandpass filters for eliminating interference and noise signals. One or more remaining signal paths include reduced filtering devices for increasing the sensitivity of a radio frequency receiver to the desired signal. Each of the receiving paths is coupled to a respective radio frequency amplifier. Provided that each radio frequency amplifier has equivalent current-source o...

A receiver includes a plurality of antennas, a selection switching unit for selectively switching between the plurality of antennas to output one of the respective output signals of the plurality of antennas having the largest induced voltage, and a unit for converting the selected one antenna output signal to an audio signal to be outputted as an output signal of the receiver. The receiver further includes a muting control unit for detecting the level of the induced voltage of the selected ante...

A method of communicating between a transponder and an interrogator. The interrogator (10) transmits a wireless RF interrogation which is received by the transponder (12). The transponder (12) then transmits a wireless RF response. The wireless RF response has a first channel response centered at frequency FDX1=RF+SC, a second channel response centered at frequency FDX2=RF-SC, and a third channel response centered at frequency FDX3=SC. The third channel response is a spurious signal resulting fr...

A space diversity receiver comprises a plurality of antenna connectors, with each of which an antenna is to be connected, a signal selecting portion for selecting one of signals from the antenna connectors, a signal processing circuit block for producing an output signal based on a signal selected by the signal selecting portion, wherein a signal sampling operation through which the signals obtained from the antenna connectors are sampled for every short period to be supplied to the signal proce...

The disclosure relates to methods and apparatus for combining a multiplicity of diversely received replicas of a signal originating in the same remote transmitter. The disclosed methods and apparatus apply, in particular, to digitally modulated sinusoidal prime-carriers or subcarriers, and base the final decision about which of the code alphabet symbols is present in each bit-symbol time slot on either: a) the maximum value of a decision index for each code alphabet letter indicated in/for the s...
